These studies were carried out to develop some easy-checking thermometers instead of taking temperature of ectum for the farmers to detect easily a diseased animal with fever. Thermometers such as pincher-type, hood-type, raser-type, stick-type, and wrap-type were devised for the experiments. The experimental animals were cattle, horse, swine, aprine, and canine. Temperature-taking parts of the body were ear, shoulder, axilla, gluteal part, and coccygeal part according o the devised thermometer. Rectal temperature was taken at the same time for the comparison of temperature between rectum nd the certain part. The difference of temperature between rectum and shoulder part using eraser-type thermometer for the domestic animals were $3.37^{\circ}C$ for cattle, $1.94^{\circ}C$ for horses, $2.04^{\circ}C$ for swine, $1.27^{\circ}C$ for caprine, $0.9^{\circ}C$ for canine. The difference of temperature between rectum and gluteal part using eraser-type thermometer for domestic animals were $3.46^{\circ}C$ for cattle, $1.98^{\circ}C$ for horses, $2.22^{\circ}C$ for swine, and $1.1^{\circ}C$ for canine. The difference of intra-individual temperature taken by eraser-type thermometer of shoulder and gluteal part were 0.3 and $0.8^{\circ}C$ for cattle, 0.7 and $1.1^{\circ}C$ for horses, 0.6 and $0.7^{\circ}C$ for swine, 0.9 and $1.1^{\circ}C$ for canine. The difference of temperature between rectum and shoulder part taken by hood-type thermometer for cattle was $3.93^{\circ}C$ and the difference of intra-individual temperature was $0.8^{\circ}C$. The difference of temperature between rectum and gluteal part taken by stick-type thermometer for cattle was $3.7^{\circ}C$ and the difference of intra-individual temperature was $0.8^{\circ}C$. The other types of thermometers than the above three were not proved to be reliable to detect temperature of domestic animals. It was concluded that hood-type, stick-type and eraser-type thermometers are recommendable devices of thermometer to detect easily the status of body temperature and that the eraser-type was proved to be a practical one of the thermometers used in this study.

Korean safflower (Carthami Flos) seed has been known to have healing effects on both bone fracture and osteoporosis. On the base of such a notice, this experiment was carried out to explore the effects of safflower seed on bone formation and bone repair. In addition, the healing mechanism was evaluated by analysing serum after feeding the seed to experimental. animals. The effect of Korean safflower seed were evaluated with 40 rats,3-month old. Forty Sprague-Dawley rats composed of 20 male and 20 female were underwent unilateral tibial defect and then fastened with unilateral fixators. The operated rats were divided into two groups depending on the composition of diet, such as positive control group fed normal diet (C-OP group) and safflower seed group fed 30% of safflower seed diet and 70% of normal diet (S-OP group). Postoperative radiographys were taken once in 2 weeks to evaluate callus formation for operated groups. In addition, a possible protein spots involved in bone recovery were examined using 2-Dimensional Gel Electrophoresis (2-DE). The comparison of the radiography between C-OP and S-OP group were showed that the safflower seed diet appeared to stimulate the formation of callus in the rat. On the images of 2-BE, it was able to identify possible five protein spots, having pl from 4 to 5 and molecular weight range from 24 to 26 kDa, involved in bone formation and repair, since no differing protein spots were found the two between groups except the five spots. No differences were observed between two groups before operation, but clear and bigger protein spots were observed from the S-OP group compared with C-OP group on 6 and 9 weeks post operation. These protein spots were, however, showed similar sizes and densities between two groups in 12 weeks later. The transformation of protein spots was suggested that these protein spots were involved in bone formation and recovery, in addition safflower seed might induce the formation of factors and activate these factors. In conclusion, this study suggest that safflower seed influence a variety of factors in the course of bone formation or the periods of remedy.

This study was performed to investigate the freezomg condition especially focused on extender composition to achieve good post-thaw viability and motility of canine sperm. Semen were collected from 6 male dogs which had been proved to be fertile in the past and were treated for freezing. Equex-STM paste was contained in both the 1st(3%) and the 2nd(7%) diluent and the 2nd diluent was added to the 1st diluent following glycerol equilibration for an hour and a half. To investigate the effect of Equex-STM paste in the extender on post-thaw canine sperm characteristics, the post-thaw viability, motility, and HOS(Hypoosmotic swelling) values were evaluated according to the different composition of extender with or without Equex-STM paste, thawing conditions, and different thawing media added to thawed semen. 1. Canine sperm removed from seminal plasma and frozen )n Sweden extender containing Equex showed higher post-thaw viability, motility, and HOS values than those frozen in the extender containing Equex-STM paste with seminal plasma and those frozen in the extender without Equex and seminal plasma. 2. Canine sperm frozen in Sweden extender containing Equex-STM paste with 5% glycerol showed higher post-thaw viability, motility, and HOS values than those frozen with 3%, 8% glycerol or 5% DMSO. 3. The canine semen frozen in Sweden extender with 5% glycerol and Equex-STM paste showed higher viability, motility, and HOS values when thawed at $70^{\circ}C$ for 8 seconds than when thawed at $37.5^{\circ}C$ for 1 min and at $18-20^{\circ}C$ for 5 min. 4. TFC (tris -fructose-citrate) and PB S (phosphate buffered saline) medium added immediately to thawed canine semen brought better viability, motility, and HOS values for the sperm than those semen added with TGC(tris-glucose-citrate) and no medium. These results indicated that Equex-STM paste in Sweden extender for freezing the canine sperm which were removed from seminal plasma brought good post-thaw viability and motility of canine sperm. Also of the freezing conditions of canine sperm with the same extender containing Equex, the concentration of 5% glycerol, the thawing condition at $70^{\circ}C$ for 8 sec, and TFC and PBS medium added to the thawed semen brought better post-thaw viability and motility of canine sperm than the other conditions used in this study.

Selectin은 조직 염증반응의 초기화에 관여하는 결합 단백질이며, 맥관내피에서 백혈구의 rolling과 tethering을 매개한다. 따라서 selectin inhibitor를 이용하여, 이들 selectin의 수용체인 sLex 에 대한 block을 유도함으로서 염증반응의 초기화를 억제할 수 있다는 가정하에, 본 연구에서는 장기이식 후 reperfusion에서 발생하는 손상에 대한 selectin inhibitor의 효과를 알아보았다. Beagle 견을 사용하여 신장이식을 실시하였다 공여 신장은 60분의 warm ischemia를 유도한 후 UW solution으로 관류하고 24시간동안 냉장보관하여 자가이식하였으며, 반대쪽 신장은 적출하였다. 술 후 7일동안 혈청 creatinine치를 측정하였다 2차실험으로, 12마리의 Beagle견을 사용하여 4시간의 reperfusion 후 조직학적 변화와 myeloperoxidase의 활성을 조사하였다. 각 실험의 대조군은 생리 식염수를,비교군은 TBC1269 (selectin inhibitor)를 신장 적출 전과 신장이식 수술 후 reperfusion 직전에 각각 투여하였다. 혈청 creatinine은 신장이식후 급격히 증가 하였으나, 두군 사이에 유의적인 차이는 없었다. 신장피질의 백혈구 침윤은, 4시간 reperfusion후 생리식염수를 투여받은 군에서 2배의 유의적인 증가를 보였다. 그러나, TBC 1269로 처리한 군에서는 백혈구의 침윤이 유의적인 억제를 보였으며, 허혈에의한 조직학적 변화도 유의적으로 적었다. 개의 신장이식 수술에서 Selectin의 차단은 warm renal ischemia에서 기인된 손상을 개선하지는 못하나, 백혈구의 침윤을 억제하므로 delayed graft function과 관련된 술 후 염증반응의 초기화를 억제하는 효과가 있는 것으로 사료된다.

Vitamin D is one of important factors involved in the regulation of bone metabolism. In osteoporosis, the therapeutic effect of vitamin D on the healing process has still been controversial. To conform the effect of $1{\alpha}$, 25 dihydroxy-vitamin $D_3$ on osteoporosis, the change of serum calcium, serum phosphorus, serum alkaline phosphatase, bone mineral density and bone mineral content of osteoporotic tibia were examined comparatively in normal control group(positive control), CFA control(negative control), CFA+$1{\alpha}$, 25 dihydroxy-vitamin $D_3$ 0.01 ug/kg group and CFA+$1{\alpha}$, 25 dihydroxy-vitamin $D_3$ 0.1 ug/kg group after osteoporosis was induced by single injection of complete Freund's adjuvant(CFA) in rats. In change of serum calcium. the significantly increased value was shown on 2nd and 5th week(P< 0.05) after treatment in $1{\alpha}$, 25 dihydroxy-vitamin D$_3$ 0.01 ug/kg group and on 3rd week(P<0.05) after treatment in $1{\alpha}$, 25 dihydroxy-vitamin $D_3$ 0.1 ug/kg group than CFA control. In change of serum phosphorus, the significantly increased value was shown on 2nd week(P<0.05) after treatment in $1{\alpha}$, 25 dihydroxy-vitamin $D_3$ 0.01 ug/kg group and on 3rd and 4th week(P<0.05) after treatment in $1{\alpha}$, ,25 dihydroxy-vitamin $D_3$ 0.1 ug/kg group than CFA control. The value of bone mineral density and bone mineral content of tibia was increased in both $1{\alpha}$,25 dihydroxy-vitamin $D_3$ 0.01 ug/kg group and $1{\alpha}$, 25 dihydroxy-vitamin $D_3$ 0.1 ug/kg group than CFA control, and the increase rate of that was higher in $1{\alpha}$, 25 dihydroxy-vitamin $D_3$ 0.1 ug/kg group than $1{\alpha}$, 25 dihydroxy-vitamin $D_3$ 0.01 ug/kg group. Considering above findings collectively, it was considered that $1{\alpha}$, 25 dihydroxy-vitamin $D_3$ was effective in preventing the complete Freund's adjuvant-induced osteoporotic decrease of bone mass.

Progesterone을 함유하고 있는 CIDR(Controlled Internal Drug Release)의 질내삽 입은 황체기를 인위적으로 연장시킬 수 있다. CIDR의 삽입이,삽입시 존재했던 우세난포 (dominant follicle)의 반응과 난포의 발육반응 그리고 2회 또는 3회의 난포주기를 가지고 있는 처려우에서 CIDR의 삽입기간동안 난포의 성장 및 발육에 어떠한 영향을 미치는가를 비교검 토하기 위하여 배란후 16일째의 처녀우 4마리에 7일동안 CIDR를 삽입하였다. CIDR의 삽입 은 발정의 발현을 억제시켰으며 그리고 발정주기의 길이를 정상 발정주기보다 유의성있게 연 장시켰다($26.3{\pm} 0.5 vs 20.8{\pm}$ 1.5일, p<0.05). CIDR의 삽입시 혈장 progesterone 농도는 $3.6{\pm}$ 2.7 ng/ml 이었으며, 17일과 23일 사이에는 2.1-4.4 ng/ml($3.6{\pm}1.2 ng/ml$) 사이를 유지했다. 혈 장 estradiol-179의 농도는 난포의 발육 및 배란전 배란난포의 성숙을 나타내는 특징적인 변화 양상을 나타래었다. 4마리의 처녀우중 2마리는 CIDR 삽입전 발정주기당 2회의 난포주기를 가진 반면, 나머지 2마리는 주기당 3회의 난포주기를 가졌다. 그렇지만 CIDR의 삽입기간동안 모든 처녀우는 주기당 3회의 발정주기를 가졌다. CIDR의 삽입전 발정주기당 3회의 난포주기 를 갖는 처녀우에서 CRR의 삽입은 세 번째 난포주기에서 배란성 우세난포의 우세기 (dominant phase)를 연장시켰다. 3회의 난포주기를 갖는 2마리에서 CIDR의 삽입후 배란난포 는 존속시간과 우세기가 유의성있게 연장되었다. CIDR의 삽입전 발정주기당 2회의 난포주기 를 갖는 다른 2마리의 처녀우에서 CIDR의 삽입후 우세난포는 곧바로 퇴행되었고 새로운 난 포주기를 형성하였으며, 우세난포의 우세기와 배란난포의 존속기간을 연장시키지 않았다. CRR의 삽입은 CIDR의 삽입후 이어지는 발정주기동안 난포의 발육 및 성장에 영향을 미치 지 않았으며 발정주기의 길이, 난포주기, 혈장 progesterone 및 estradiol-179 농도에 영향을 미치지 않았다. 결과적으로 황체기 후반부에 CIDR의 삽입은 CIDR삽입전 발정주기동안 3회 의 난포주기를 갖는 처녀우에서 배란성 우세난포의 발육과 배란까지의 기간을 연장시켰고 2회 난포주기를 갖는 처녀우에서는 우세난포를 곧바로 퇴행시킨후, 새로운 난포주기를 형성 하였다.

Background: The study was planned to show the status of indoor microorganisms and the status of the reduction device in the military dog clinic. Methods: Airborne microbes were analyzed according to the number of daily patient canines. For identification of bacteria, sampled bacteria was identified using VITEK^®2 and molecular method. The status of indoor microorganisms according to the operation of the ventilation system was analyzed. Results: Airborne bacteria and fungi concentrations were 1000.6 ± 800.7 CFU/m³ and 324.7 ± 245.8 CFU/m³. In the analysis using automated identification system, based on fluorescence biochemical test, VITEK^®2, mainly human pathogenic bacteria were identified. The three most frequently isolated genera were Kocuria (26.6%), Staphylococcus (24.48%), and Granulicatella (12.7%). The results analyzed by molecular method were detected in the order of Kocuria (22.6%), followed by Macrococcus (18.1%), Glutamicibacter (11.1%), and so on. When the ventilation system was operated appropriately, the airborne bacteria and fungi level were significantly decreased. Conclusion: Airborne bacteria in the clinic tend to increase with the number of canines. Human pathogenic bacteria were mainly detected in VITEK^®2, and relatively various bacteria were detected in molecular analysis. A decrease in the level of bacteria and fungi was observed with proper operation of the ventilation system.

Background: Golf is a popular sport involving overhead activity and engagement of the rotator cuff (RC). This study aimed to determine to what level golfers were able to return to golf following RC repair, the barriers to them returning to golf and factors associated with their failure to return to golf. Methods: Patients preoperatively identifying as golfers undergoing RC repair at the study centre from 2012 to 2020 were retrospectively followed up with to assess their golf-playing status, performance and frequency of play and functional and quality of life (QoL) outcomes. Results: Forty-seven golfers (40 men [85.1%] and 7 women [14.9%]) with a mean age of 56.8 years met the inclusion criteria, and 80.1% were followed up with at a mean of 27.1 months postoperatively. Twenty-nine patients (76.3%) had returned to golf with a mean handicap change of +1.0 (P=0.291). Golf frequency decreased from a mean of 1.8 rounds per week preinjury to 1.5 rounds per week postoperatively (P=0.052). The EuroQol 5-dimension 5-level (EQ-5D-5L) index and visual analog scale (EQ-VAS) score were significantly greater in those returning to golf (P=0.024 and P=0.002), although functional outcome measures were not significantly different. The primary barriers to return were ipsilateral shoulder dysfunction (78%) and loss of the habit of play (22%). Conclusions: Golfers were likely (76%) to return to golf following RC repair, including mostly to their premorbid performance level with little residual symptomatology. Return to golf was associated with a greater QoL. Persistent subjective shoulder dysfunction (78%) was the most common barrier to returning to golf.
